JPOG's lost music

I absolutely love the music of this game, and i've noticed some stuff is missing.

I'm an armature composer, and i am the person who uploaded the unreleased track to Youtube (if you've heard it). i will try to explain why i think a lot of music is lost.

i'm sure most of you have seen the trailer for the game on youtube, half way through the trailer, it cuts to a song that is nowhere to be found in the game. first i will talk about this song and what is missing from it:

1: seems pretty obvious it cuts to a certain part of the song, no song would suddenly start like that it would at the very least have a build up. and the reason i think it cuts to different song and that it's not an addition to the regular JP theme we first hear, is because the JP theme sounds exactly like the "Flyby" theme we have in the game. so leads me to believe the editors for the trailer just got the soundtrack and put specific parts of the soundtrack in the trailer which they thought would fit.

2: at 00:59 in the trailer there seems to be a cut in the song too, however i do believe it's the same song, just at a different point. the reason i think it's a cut, is because it seems quite abrupted especially for orchestral music, normally you would have some kind of bridge to get to that point.

Other songs: I know for a fact there is multiple lost songs. a while back i emailed the composer of the game Stephan Schütze (he has a website) after noticing he had uploaded a song from the game which was never used and asked him if there is anything else he could possibly share. he replied a few days after and said he couldn't share more because of copyright (the reason he could share the unreleased song is because it has no melodies from JP) which is sad, but 100% understandable. (I emailed him in 2018)

Sorry if this seems a little obsessive, and i'm sure nothing will come out of this, but i thought it wouldn't hurt to try and put this out there.
